Struct FakeFrameInjector 

pub struct FakeFrameInjector { /* private fields */ }

Test-only handle for simulating a live Frame::Video arrival in unit tests. See StreamSource::start_inert_for_test_with_gap_and_injector.

pub (not pub(crate)) so tests/fixture_replay.rs can drive production’s gap-detection ticker from an integration test. The #[cfg(any(test, feature = "test-util"))] gate on the struct + impl keeps this out of release builds; the test-util feature is only pulled in by bairelay’s own [dev-dependencies] self-reference.

Implementations

impl FakeFrameInjector

pub fn inject_fake_video_frame(&self)

Mark the source as having just received a real live video frame. Mirrors a SUBSET of the state updates that reader_task performs after a successful BcMedia::Iframe / Pframe translation.

Of production’s four live-frame state mutations, this helper replicates two and skips two:

Replicated:

• last_live_frame_at — bumped to Instant::now() so the gap ticker sees a fresh live frame.
• gap_state — forced back to GapState::Live.

Skipped:

• last_emitted_pts_90khz — real reader advances this from the decoded frame’s PTS so replay can synthesize continuous timestamps; tests that assert PTS continuity must set it manually.
• last_emit_wallclock_at — real reader stamps wall-clock per emit so the Bridging ticker knows when to fire; tests that depend on ticker phase must set it manually.

Does NOT broadcast — use Self::broadcast_live_video_frame when a downstream subscriber needs to actually see the frame.

pub fn broadcast_live_video_frame(&self, frame: Frame)

Near-reader-task-equivalent “live video frame arrived” event: broadcast frame on the source’s tx channel AND update the gap-detection markers so the ticker stays in Live state. Used by the Task 11 integration test in tests/fixture_replay.rs to drive a real StreamSource through Live → Bridging → Live transitions with frames that actually reach attached RTSP subscribers.

NOT a full production mock. Delegates to Self::inject_fake_video_frame for state updates, which only touches last_live_frame_at + gap_state. Production’s last_emitted_pts_90khz and last_emit_wallclock_at are NOT advanced here — a future test author who needs PTS-continuity or ticker-phase accuracy must write those directly.
